Steiger Lake Wetland Restoration
Overview
In an effort to reduce phosphorous levels and improve water quality in Steiger Lake, the Minnehaha Creek Watershed District (MCWD) restored a partially drained wetland in Victoria. Now, the wetland is a natural stormwater treatment system for a 250-acre drainage area, and reconnects that water to small ponds throughout the restored area. To ensure there are no impacts on historic water levels, MCWD installed a weir at the wetland. MCWD also expanded a city-owned pond directly north of Highway 5 at Steiger Lake Lane. Both the wetland and the pond now effectively store and filter polluted water before it enters Steiger Lake.
MCWD’s 2007 Water Resources Management Plan identified a goal to reduce external phosphorus loading to Steiger Lake, which is part of a chain of lakes and wetlands that flow to Parley Lake before ultimately discharging into Halsted Bay on Lake Minnetonka. By restoring the wetlands that connect to Steiger Lake, MCWD was able to improve water quality both in the lake and ultimately in Halsted Bay, which is among the most degraded bays on Lake Minnetonka.
